 ... listening to the discourse of "his ancient," or regaling him "with sweet converse"; and thus they onward jog, until the sign of the "Greyhound," stretching quite across the main street, greets their expectant optics, and seems to forbid their passing the open portal below. In they wend then, and having seen their horses "sorted," and the collar marks (as much as may be) carefully effaced by the shrewd application of a due quantity of grease and lamp-black, ...

... goes beyond the eye, and one has to depend upon the feel; and when one has once learned what a delicate affair touch is, one gets a horror of all coarse work, and is ready to forgive any amount of feebleness, sooner than that boldness which is akin to impudence. In optics the distinction is easily seen when the work is put to trial; but here too, as in drawing, it requires an educated eye to tell the difference when the work is only moderately bad; but with "bold" work, nothing can be seen but distortion ...

No—but a hostess engaged in suckling and bathing her brats, or in studying chemistry and optics with some dirty school-master, who is given the seat of honour at table and a pavilion in the park to which he may retire when weary of the homage of the great; while as for the host, he is busy discussing education or political ...

While writing his treatise on Optics, it is said he confined himself entirely to bread, with a little sack and water; and I have no doubt that his remarkable equanimity of temper, and that government of his animal appetites, throughout, for which he was so distinguished to the last hour of his life, were owing, in no small ...

Stage effect required a study of perspective, variation of light, and a knowledge of the laws of optics. The slight outline drawing of his predecessor was probably superseded by effective masses to create illusion. This was a distinct advance toward nature. Apollodorus (fl. end of fifth century B.C.) applied the principles ...

Yet those same bleared optics had a strange, penetrating power, when it was their owner's purpose to read the human soul.

There was nothing in known science outside of optics, that could in any way be blended with the Blind Spot.

The point is, can we make a better one or must we be content with patching up the old one? Take an illustration. Scientists tell us that from the point of view of optics the human eye is a clumsy instrument poorly contrived for its work. A certain great authority once said that if he had made it he would have been ashamed of it. This may be true. But the eye unfortunately is all we have to see by. If we destroy ...

He studied Italian, Greek, mathematics; Maclaurin's Fluxions served to "unbend his mind"; Smith's Harmonics and Optics and Ferguson's Astronomy were the nightly companions of his pillow.

... extending far and wide, but superficially, sometimes with exactness over particular departments, sometimes occupied together on one and the same portion, sometimes holding one part in common, and then ranging on this side or that in absolute divergence one from the other. Thus Optics has for its subject the whole visible creation, so far forth as it is simply visible; Mental Philosophy has a narrower province, but a richer one. Astronomy, plane and physical, each has the same subject-matter, but views it or treats it differently; lastly, Geology and Comparative ...

The modern meaning of pencil, which still meant painter's brush in the 18th century, is due to association with pen. The older sense survives in optics and in the expression "pencilled eyebrows."
